Abstract

A system manufactures a tire assembly. The system includes a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub, a plurality of internal arcuate members for positioning a reinforcing layer of the about the core, the internal arcuate members each being wrapped with a reinforcement layer, the internal arcuate members being disposed in spaces circumferentially between the extensions of the core, a first side plate for securing the internal arcuate members in place relative to the core; and a second side plate for securing the core and internal arcuate members to each other.

First claim

What is claimed:

1. A system for manufacturing a tire assembly, the system comprising:
a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub;
a plurality of internal arcuate members for positioning a reinforcing layer about the core, each of the internal arcuate members each being wrapped with a reinforcement envelope, each of the internal arcuate members being disposed in spaces circumferentially between the extensions of the core;
a first side plate for securing each of the internal arcuate members in place relative to the core; and
a second side plate for securing the core and each of the internal arcuate members to each other wherein the reinforcing layer comprises calendered fabric and rubber compound treatments applied to an outer surface of the core across a full 360 degree circumference of the core with a shear band structure applied over the reinforcing layer.

2. The system as set forth in claim 1 wherein each reinforcement envelope comprises calendered fabric and rubber compound treatments.

3. The system as set forth in claim 1 wherein another reinforcing layer comprising calendered fabric and rubber compound treatments is applied to an outer surface of the core across a full 360 degree circumference of the core.

4. The system as set forth in claim 1 further including wedges disposed on each of the reinforcement envelopes in depressions between the extensions of the core and each of the internal arcuate members.
